UN Ends 35-Year Peacekeeping Mission in Western Sahara After Vetoes

The United Nations ended its peacekeeping mission in Western Sahara after 35 years. MINURSO ceased operations following the failure of the Security Council to adopt a resolution that would have extended its mandate. Russia vetoed a United States draft that supported Moroccan sovereignty over the territory. A Russian proposal to continue the mission without that language did not secure enough votes.

MINURSO was established in 1991 to monitor a ceasefire between Morocco and the Polisario Front and to prepare for a referendum on the territory's status. The referendum never took place. The mission's observers remained in place through successive mandate renewals. The final disagreement in the Council removed the legal basis for continued presence.

Morocco controls most of the territory and has invested in infrastructure and settlement. The Polisario Front administers camps in Algeria and maintains a claim to independence. Algeria supports the Polisario position. The United States has recognised Moroccan sovereignty in recent years. Russia has opposed that recognition and blocked language that would have reflected it in a Council resolution.

The end of the mission removes the only international military observers from the ceasefire line. No replacement mechanism was agreed. Local populations on both sides of the berm now lack the limited monitoring that MINURSO provided. Humanitarian access to the camps and to Moroccan-controlled areas continues through other channels, but the specific verification role ends.

The 35-year duration makes MINURSO one of the longer-running UN peacekeeping operations. Its original mandate assumed a political process that stalled. Successive secretaries-general reported little progress on the referendum while the mission's military component remained static. The veto sequence in 2026 closed the remaining options for extension.

Regional governments will now manage the situation without UN military observers. Morocco has stated that its control is irreversible. The Polisario Front has not announced a change in its military posture. The absence of observers increases the risk that minor incidents go unrecorded and escalate. Neighbouring states, including Algeria and Mauritania, face the practical consequences of any renewed tension.

The concrete outcome is the termination of a mission that began in 1991. The Security Council could not produce a text acceptable to both the United States and Russia. That deadlock ends the formal UN military presence. Any future arrangement will require a new agreement among the parties and the Council members who previously sustained the operation.
